  • Patent number: 11065459
    Abstract: An implantable medical device (IMD) is configured with a pressure sensor. The IMD includes a housing and a diaphragm that is exposed to the environment outside of the housing. The diaphragm is configured to transmit a pressure from the environment outside of the housing to a piezoelectric membrane. In response, the piezoelectric membrane generates a voltage and/or a current, which is representative of a pressure change applied to the housing diaphragm. In some cases, only changes in pressure over time are used, not absolute or gauge pressures.

  • Patent number: 10994145
    Abstract: An implantable cardiac monitor (ICM) may be configured to be deployed subcutaneous, submuscular, or substernal at a position that enables the ICM to detect cardiac activity. In some cases, the ICM includes a housing that includes a body portion and a tail portion. A first electrode may be disposed adjacent a first end of the body portion, a second electrode may be disposed adjacent a second end of the body portion and a third electrode may be disposed adjacent a tail end of the tail portion. A controller may be disposed within the housing and may be operably coupled to the first electrode, the second electrode and the third electrode. The controller may be configured to select a pair of the first electrode, the second electrode and the third electrode to use for sensing cardiac electrical activity and to communicate information about the sensed activity to a second medical device.

  • Publication number: 20210106271
    Abstract: Methods and systems for use of the Q-wave to R-wave interval to guide placement of a leadless cardiac pacemaker are disclosed. An implant delivery device is equipped with sensing electrodes to sense R-wave onset in a ventricle of a patient's heart to allow placement at a location of last or latest onset of the R-wave. Guidance tools are provided to assist in determination of the Q-wave to R-wave interval during implantation. For a chronic system, a cooperative approach is disclosed in which an implantable medical device and a leadless cardiac pacemaker exchange data to determine Q-wave to R-wave intervals and enhance cardiac resynchronization therapy delivery by the leadless cardiac pacemaker.

  • Publication number: 20210038904
    Abstract: Implantable medical devices (IMD), such as but not limited to leadless cardiac pacemakers (LCP), subcutaneous implantable cardioverter defibrillators (SICD), transvenous implantable cardioverter defibrillators, neuro-stimulators (NS), implantable monitors (IM), may be configured to communicate with each other. In some cases, a first IMD may transmit instructions to a second IMD. In order to improve the chances of a successfully received transmission, the first IMD may transmit the instructions several times during a particular time frame, such as during a single heartbeat. If the second IMD receives the message more than once, the second IMD recognizes that the messages were redundant and acts accordingly.

  • Patent number: 10881869
    Abstract: Near-field energy transmitters for charging a rechargeable power source of an implantable medical device (IMD). In some cases, the transmitter may include an output driver that may drive a transmit coil such that near-field energy is transmitted to the IMD at a determined frequency. In some cases, the IMD may include a receiving coil that may capture the near-field energy and then convert the near-field energy into electrical energy that may be used to recharge the rechargeable power source. Since the rechargeable power source does not have to maintain sufficient energy stores in a single charge for the entire expected life of the IMD, the power source itself and thus the IMD may be made smaller while still meeting device longevity requirements.

  • Patent number: 10874861
    Abstract: A ventricular implantable medical device that is configured to detect an atrial timing fiducial from the ventricle. The ventricular implantable medical is configured to deliver a ventricular pacing therapy to the ventricle based on the detected atrial timing fiducial. If the ventricular implantable medical device temporarily fails to detect atrial activity because of noise, posture, patient activity or for any other reason, an atrial implantable medical device may be configured to communicate atrial events to the ventricular implantable medical device and the ventricular implantable medical device may synchronize the ventricular pacing therapy with the atrium activity based on those communications.
